Detailed Description

The following describes the embodiments of the present utility model in further detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present utility model and are not intended to be limiting.

In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "top", "bottom", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

As shown in fig. 1 to 3, the present utility model provides a detachable tool mounting apparatus comprising a tool mounting shaft 1, a sleeve 2 sleeved outside the tool mounting shaft 1, a press block 4, and a first fastener 51, the tool mounting shaft 1 comprising a mounting portion 11 for receiving a tool 3, the first fastener 51 penetrating through the sleeve 2 to press the press block 4, and fixing the tool 3 between the press block 4 and the mounting portion 11. The knife 3 is in particular a straight knife, V-knife or a knife with other knife surface shapes.

In the detachable tool mounting device provided by the utility model, the tool 3 is detachably connected with the tool mounting shaft 1, and when the tool 3 needs to be replaced or maintained, the tool 3 can be taken out of the mounting part 11 by sequentially removing the first fastening piece 51 and the pressing block 4, so that the operation is very simple.

In one embodiment of the present utility model, the first fastener 51 includes a first head 511 and a first body 512 connected to each other, the first head 511 having an outer diameter smaller than that of the first body 512; the shaft sleeve 2 is provided with a first opening 21, the first main body 512 is in threaded connection with the first opening 21, and the first head 511 is matched with a clamping groove formed on the pressing block 4. By screwing the first body 512 into the first opening 21, the first head 511 gradually enters the clamping groove on the press block 4 until the junction of the first head 511 and the first body 512 is limited by the press block 4, and the first fastener 51 is in place, and continuously provides a pressing force to the press block 4 toward the cutter 3. The pressing block 4 and the cutter 3 are made of metal materials, and a first magnetic attraction piece 13 for attracting the cutter 3 and a second magnetic attraction piece 14 for attracting the pressing block 4 are further arranged in the mounting part 11. The first magnetic attraction member 13 and the second magnetic attraction member 14 are specifically magnets. After the operator removes the first fastening piece 51, the pressing block 4 is still absorbed in the mounting part 11 by the second magnetic attraction piece 14, and the pressing block cannot automatically fall off from the mounting part 11 due to the fact that the jacking force provided by the first fastening piece 51 is lost; then, after the operator manually removes the pressing block 4, the cutter 3 is still absorbed in the mounting portion 11 by the first magnetic attraction piece 13, and the cutter is not automatically separated from the mounting portion 11 due to the disappearance of the pushing force provided by the pressing block 4. The arrangement greatly enhances the use safety of the device, and can avoid operation risks and part damage caused by falling off of the pressing block 4 and the cutter 3.

In order to ensure the connection and fastening between the shaft sleeve 2 and the tool mounting shaft 1, a second opening 22 extending along the radial direction of the shaft sleeve 2 is further formed in the shaft sleeve 2, a connection hole 15 extending along the radial direction of the mounting portion 11 is formed in the mounting portion 11, and the connection hole 15 and the second opening 22 are connected through a second fastening member 52.

Further, the aperture of the connection hole 15 is larger than that of the second opening 22, and the second fastener 52 includes a second head 521 and a second body 522 connected to each other, the second head 521 is engaged with the second opening 22, and the second body 522 is screwed with the connection hole 15. In the initial state, the second fastener 52 is completely located in the connection hole 15; when it is desired to connect the sleeve 2 and the tool mounting shaft 1, the second fastener 52 can be rotated through the second opening 22 on one side so that the second head 521 gradually enters the second opening 22 on the other side until the junction of the second head 521 and the second body 522 is restrained by the inner wall of the second opening 22, and the second fastener 52 is in place. This arrangement is easy to handle and prevents the second fastener 52 from being lost.

Further, the tool mounting shaft 1 further includes a connecting portion 12 coaxially connected to the mounting portion 11, and the connecting portion 12 is used for connecting with other structures capable of driving the tool 3 to rotate or perform lifting motion. In order to prevent the sleeve 2 and the tool connecting shaft 1 from being released due to impact force generated when the tool 3 is driven to lift by other structures, it is preferable that a limit step 111 is further provided at the bottom of the mounting portion 11, and the bottom of the sleeve 2 abuts against the limit step 111. The limit step 111 can provide a supporting force to the sleeve 2 to buffer downward impact.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present utility model, and these modifications and substitutions should also be considered as being within the scope of the present utility model.
